Investments have previously been granted to improve the evaporation plant and the recovery boiler at Vallvik. This work will be carried out during the planned maintenance shutdown at the mill in October 2010. The investments now mean that it is possible to use and incinerate more organic material and to reduce the size of the external water treatment plant, which has now been approved.
The new water treatment plant will be put into operation during the autumn of 2011 when it is planned to implement the final stage of the investment programme.
"The investment programme that is going ahead at Vallvik Mill resolves long-standing discussions with various levels of the environmental agencies, at the same time as expanding the production of bioenergy at the mill and increasing production capacity by 20 per cent to an annual figure of 242,000 tonnes", explains Ole Terland, President of Rottneros.
